- the invention relates to a method and a system for eavesdropping of phone calls.
- the phone is currently being tapped into the area the Federal Republic of Germany through the so-called Telecommunications Surveillance Ordinance regulated according to the one to be heard Telephone call recorded in a recording center which is subordinate to an investigative authority.
- the useful signal that essentially the information content of the telephone conversation represents, i.e. the relevant conversation information contains, and data summarized in a data set, which are suitable for identifying the target person, e.g. e.g. the international mobile subscriber number of the Mobile station, MSISDN for short, will be the recording center fed.
- the useful signal in the form of digital call data and the data set secured so that an authorized user, e.g. a detective charged with monitoring the target can listen to the recorded phone call.
- wirelesstapping is not just recycling an acoustic signal, but generally receiving and understand the evaluation of the conversation information is.
- the known interception method has the disadvantage that the consumer the conversation held by the target person only on Location of the recording center. It is special to him not possible the target person who in turn by Use of the mobile station during the phone call is not tied to a fixed location at the same time track and eavesdrop. This limits the efficiency of the listening process and the associated fight against crime clearly one.
- US-A-5,590,171 describes a method for eavesdropping on telephone calls described. With this procedure you can make phone calls within an intelligent network, IN for short be bugged. A service-specific IN node receives Identification information corresponding to the telephone call to be listened to assigned. Based on this information the IN node establishes a communication link between the two communicating participants. Furthermore he makes sure that the conversation is for eavesdropping authorized participants of the conversation and / or a recording device is forwarded. One to protect communication participants certain that preceded the listening process Call recording sees that discussed in US-A-5,590,171 Procedure not before.
- the object of the invention is a method and a system to indicate that it is possible to eavesdrop on telephone calls, especially of mobile participants to be monitored, to make it more efficient.

- the playback device can be connected to the fixed network immediately the communication link to the Establish eavesdropping equipment and that from the recording center requested call data in the form of a playback signal send to the listening device.
- the playback signal can be an analog or be a digital signal. In the latter case, the call data from the playback device essentially be forwarded unchanged to the listening device.
- the invention accordingly enables so-called online transmission of the telephone call to be listened to during this still ongoing.
- the playback device offers the possibility of that Recording center received phone calls to individuals Distribute users.
- a consumer for example a detective charged with monitoring the target, is therefore not forced to target the person as before eavesdropping from the recording center.
- a mobile station as a listening device eavesdrop on the target person during the opposition so that a combating crime more efficiently and flexibly than before is possible.
- the mobile station as a listening device offers that Consumers also have the advantage of easy handling as well the almost perfect camouflage as a suspect mobile subscriber.
- the method according to the invention is not based on that just explained Limited situation where the target person has a mobile station used.
- Telephone calls can also be listened to be the target person on a stationary phone leads.
- a stationary telephone can also be used as a listening device be used. So the invention is a listening process given that on all practically relevant discussion and Listening situations is applicable.
- the method according to the invention enables a mobile subscriber eavesdropping without interfering with the radio transmission need to be between the mobile station of the mobile subscriber and a base transceiver station of the mobile communication network takes place. This is of great advantage since the between the mobile station and the base transceiver station exchanged signals are encrypted and eavesdropping of these signals is connected with great effort.
- the coupling of the playback device to the recording center on the one hand and the landline on the other hand, to implement without major technical effort is, it is clear that the method presented is also quite inexpensive.
- Establishing the communication link from the playback device one contained in the selected comparison data set Dialed the number assigned to the listening device is.
- the given by the stored phone number Information enables the playback device to connect to the person responsible for monitoring the target person Immediately produce needs, so that this Listen to a phone call without a significant delay can.
- tax data When establishing the communication link between the Playback device and the listening device of the consumer tax data can be accessed, which in the selected comparison data record are included.
- the Tax data can be created for every consumer, i.e. for each individual comparison data record, created individually, so that a flexible and individually optimized connection setup is guaranteed.
- Control data contained can the listening device Additional information will be transmitted. So the consumer for example after establishing the communication connection Predefined, individually created text sequences leaked to him information about the listened Deliver target person.
- the information content of the phone call can be in the recording center by a digital recording device be secured. Is this fed to the recording center Useful signal an analog signal, so this can the recording device converted into digital conversation data become.
- the data record can for example the international mobile subscriber number MSISDN, the international mobile device identifier IMEI and / or contain the international mobile subscriber identifier IMSI.
- MSISDN international mobile subscriber number
- IMEI international mobile device identifier
- IMSI international mobile subscriber identifier
- the playback device can, for example, with the recording center over a local data network, also called LAN, be connected.
- the recording center transmits via this data network the call data and the data set to the Reproduction device.
- the interface between the playback device and the fixed network can be an interface specified according to the known ISDN standard.
- the interface can be designed as an S 0 interface or, if more powerful communication is desired, as an S 2M interface.
- Such an identifier is, for example personal identification number, also called PIN number, which is transmitted using the DTMF method. It is advantageous the PIN number at the interface between the playback device and decode the landline.
- a system for Listening to phone calls given.
- the invention is explained for the case that the target object to be listened to, i.e. usually the target person, one within a operated according to the known GSM standard public mobile communication network of active mobile subscribers is from an authorized user, for example a detective using one mobile station functioning as a listening device is intercepted.
- the construction and operation of the mobile communication network are known per se, only the components in the figure of the mobile communication network shown for understanding the invention are required.
- the following to those necessary to eavesdrop on phone calls Measures received only in the context relevant to the invention.
- a situation is illustrated in the figure, in which the target person via a mobile station 10, hereinafter also called target station, with one not shown in the figure Interlocutor communicates.
- the destination station sends a telephone call to a base transceiver station 12 via radio according to the GSM standard encrypted message signal which is essentially a representing the information content of the telephone call Contains useful signal. Signaling data are also used with the useful signal transferred, which is known for the Control the establishment of the connection process required.
- the useful signal transmitted according to the GSM standard is a digital one Signal is, in the following for the useful signal
- the term "call data" is used.
- the call data are stored in the base transceiver station 12 decrypted and fed to a mobile switching center 14. From there, the call data, which the Represent call information, and to a record summarized subscriber identifiers that provide identification allow the target person on the designated 16 and 18 and unspecified for the reasons mentioned above Transfer paths to a recording center 20.
- the data record can be used as subscriber identifiers next to or on International mobile subscriber number, e.g. the international mobile device identifier, IMEI for short, and / or the international mobile subscriber identifier, in short IMSI included. Furthermore, subscriber identifications can be made in the data record be included, for example a one-touch dial number with a call diversion or a location identifier of the participant.
- International mobile subscriber number e.g. the international mobile device identifier, IMEI for short, and / or the international mobile subscriber identifier, in short IMSI included.
